SLIDE FASTENER Filed Feb. 2, 1962 v INVENTOR. Lou/5 H Mom/v HTTORA/EY United States Patent 3,129,479 SLIDE FASTENER Louis H. Morin, Bronx, NY. (125 Beechwood Ave., New Rochelle, N.Y.) Filed Feb. 2, 1962, Ser. No. 170,648 Claims. (Cl. 24205.12)

This invention relates to sliders and, particularly, to the body structure of sliders for use in conjunction with separable fastener stringers, wherein the scoops are disposed on one surface only of the stringers and, wherein, the tapes of the stringers have extended cover portions adapted to overlie scoops of the companion stringer in fully covering scoops of both stringers. More particularly, the invention deals with a slider structure, wherein the connecting web between the side walls of the slider body include deep recesses or channels for guidance of the extended cover portions of the stringer tapes into and through the double channel portions of the slider body.

The novel features of the invention will be best under stood from the following description, when taken together with the accompanying drawings, in which certain ernbodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a plan view of the body portion of a slider made according to my invention, omitting the showing of accessories to the slider, with parts of the construction broken away and in section and illustrating portions of two stringers diagrammatically in the slider body.

FIG. 2 is a section substantially on the line 22 of FIG. 1 showing a central section through the scoop of one stringer and illustrating part of the scoop of another stringer in the background and omitting other background showing.

FIG. 3 is a section substantially on the line 33 of FIG. 1 illustrating only the slider body and indicating tapes of two stringers in part in dot-dash lines; and

FIG. 4 is a view, generally similar to FIG. 2, showing a modified form of stringer construction.

In illustrating one adaptation and use of my improved slider construction, I have shown in the several figures the slider body proper with no attempt to illustrate conventional pulls and other accessories which are commonly employed in devices of this type and kind, these being omitted to simplify the present disclosure and to concentrate primarily on the structural features of the slider body. The slider comprises opposed substantially similar walls and 11 and, for purposes of description, the wall 10 can be considered the top wall and the wall 11 can be considered the bottom wall. These walls differ simply from the standpoint that the wall 10 has a projecting flange 12 at one side, namely the left side of FIG. 2; whereas, the wall 11 has a similar flange 13 at the opposed side of the slider body. Both of the flanges 12 and 13 terminate short of the opposed walls of the slider body to form passages, as at 14 and 15, through which the tapes 16 and 17 of two separable fastener stringers are adapted to pass. The walls 10 and 11 are joined at the wide flared end of the slider body in a connecting web 18, partially shown in section in FIG. 1, and the inner contracted end 19 of this web, in combination with the flared flanges 12 and 13, divide the wide end of the slider into diverging channels 20, 21, which join in a single channel 22 at the narrow end of the slider body. This is generally common to sliders of this type and kind.

Considering FIG. 3 of the drawing, a section has been shown through part of the web 18, this section passing through grooves or recesses 23 and 24 on opposed sides of the web, 23 being adjacent the wall 11, and 24 being adjacent the wall 10.

The grooves or recesses 23 and 24 overlap each other ice at the inner contracted end 19 of the web 18, as will clearly appear from the showing in FIG. 1 of the drawing.

Scoops 25 are fixed to one surface only of the stringer tape 16 on the beaded portion 26 of this tape and similar scoops 27 are fixed to one surface only of the stringer tape 17, including the beaded portion 28 thereof, the scoop 27 being diagrammatically shown, in section, in FIG. 2 of the drawing and a portion of two scoops 25 are shown in plan in FIG. 1 of the drawing, it being understood that the scoops of each stringer are generally of the same construction. No further detailed description of the scoops will be given, as the stringers with the scoops thereon as employed in conjunction with this slider form the subject matter of a companion application filed of equal date herewith.

The stringers in question, or the tapes thereof, each include extended cover portions 29 and 30 on the tapes 16 and 17, the cover portion 29 overlying the scoops 27 of the tape 17; whereas, 30 overlies the scoops 25 of the tape 16 when the stringer tapes are in coupled relationship to each other, as diagrammatically illustrated in FIG. 2 of the drawing. The scoops of each of the stringers are guided into or through the channels 20, 21 of the wide flared end portion of the slider body; whereas, the extended cover portions 29 and 30 are guided into and through the slider body in passage through the grooves or recesses 23 and 24, respectively, as diagrammatically illustrated in FIG. 1 of the drawing. In other words, the scoops of the stringers are primarily guided into and through the slider body by the flanges 12 and 13 and guidance through the double channels 20, 21 of the slider body is assisted by passage of the extended cover portions 29 and 30 through the grooves or recesses 23 and 24, respectively. Accordingly, it will be apparent that the extended cover portions, in addition to providing complete coverage of the scoops of coupled stringers, as illustrated in FIG. 2 of the drawing, also serve as means for guidance of the stringer tapes through the wide or flared channelled end of the slider body.

In FIG. 4 of the drawing, I have shown a slight modification of the structure shown in FIGS. 1 to 3, inclusive, and, in FIG. 4, 10', 11 represent walls, similar to 10 and 11, where the flanges of said walls are reversed, in other words, the flange 12' of the wall 10 is on the right side and the flange 13' of the wall 11' is on the left side. Here, the spacing between the edges of the flanges and the opposed walls is increased, as indicated at 14 and 15'. It will also appear that the stringer tapes 16, 17 extend through the spaces 15', 14', which is again in reverse to the condition of FIG. 2. This is occasioned by virtue of attachment of a portion of the stringer tapes to inner mounted end portions of scoops 25', 27, as indicated at 31 and 32 in FIG. 4. In other words, with this construction, the flanges 12', 13' are of wider spacing and these flanges ride over the tape portions 31 and 32 in coupling and uncoupling the fastener stringers. As a result of this arrangement, it will appear that a more complete coverage or enclosure of the coupled scoops is provided. In FIG. 4, 29' and 30' represent the extended cover portions of the stringer tapes 16, 17, respectively, similar to the showing in FIG. 2 of the drawing and, aside from the modification defined, the structure of FIG. 4 will be the same as that shown in FIG. 2 and the slider, including the walls 10, 11', will have a similarly constructed wide end and web portion, with grooves or recesses therein, similar to the grooves or recesses 23, 24 of FIGS. 1 and 3 of the drawing.

It will be understood that the coupling end portions of the scoops of the stringers can be formed in any desired manner, as taught, for example, in the companion application hereinbefore referred to and, for this reason, it is not deemed necessary to specifically refer to the structure of these coupling ends, as diagrammatically illustrated, in part, in FIG. 1 of the drawing. As with other devices of this type and kind, the scoops of one stringer interlock with the scoops of the companion stringer and this interlocked relationship is diagrammatically illustrated in FIGS. 1 and 4 of the drawing.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent is:
